What clue might indicate an electrical hazard?

The presence of warm tools or cords can be a significant indicator of an electrical hazard. When tools or electrical cords become warm to the touch, it suggests that they are carrying more current than they are designed to handle, which can lead to overheating and potentially cause a fire. This condition is often caused by factors such as poor connections, damaged insulation, or overloading circuits, all of which pose serious safety risks.

In contrast, other clues like a burning smell or frequent circuit breaks also signal potential electrical issues, but they may not specifically indicate the danger posed by warm tools or cords. Flickering lights can be a symptom of voltage fluctuations or issues with the connection to the light fixture but do not directly reflect heat-related hazards. Understanding these differences is critical for identifying and addressing electrical hazards effectively.
